While running the SpashScreen test ie. jdk/test/close/java/awt/SpashScreen/test18.sh
the dog will forever be wagging its tail at you.

The test in itself will fail with the following error in the logs:
Exception in thread "main" java.lang.UnsatisfiedLinkError: sun.awt.X11.XToolkit.getTrayIconDisplayTimeout()J
